MIB-II defines a set of manageable objects in various layers of the TCP/IP protocol
suites. MIB-II covers all the manageable objects from Layer 1 to Layer 4, and, as a
result, it is the major SNMP MIB supported by all vendors in the networking industry.
The AGENT-2 S41D advanced switch supports a complete implementation of SNMP
Agent and MIB-II.
7.3 RMON MIB (RFC 2819) and Bridge MIB (RFC 1493)
The AGENT-2 S41D switch provides hardware-based RMON counters in the system
chipset. The switch manager CPU polls these counters periodically to collect the
statistics in a format that complies with the RMON MIB definition.
7.3.1 RMON Groups Supported
The AGENT-2 S41D supports the following RMON MIB groups defined in RFC 2819:
- RMON Statistics Group – maintains utilization and error statistics for the switch
port being monitored.
- RMON History Group – gathers and stores periodic statistical samples from the
previous Statistics Group.
- RMON Alarm Group – allows a network administrator to define alarm thresholds
for any MIB variable. An alarm can be associated with Low Threshold, High
Threshold, or both. A trigger can trigger an alarm when the value of a specific
